The Constructed Wetlands Association The CWA is a professional organization that represents all those interested in design, constructing or researching in constructed wetlands. Set up by some of the early researchers in the field such as Paul Cooper from WRc in 1999. It runs CPD courses, meetings, conferences as well as accreditation for those who want a career in this popular area. It also has a very useful website with a wide range of online resources.
